Answer 1

Thanvi bought a notepad=rs 8 3/4

Thanvi bought a pen= Rs 10 2/5

Thanvi Should pay =?

8 3/4+10 2/5=35/4+52/5=35×5+52×4/20=140+208/20=348/20=17.4(or)

87/5

Answer 2

Answer:

Cost of a notebook =

$₹8 \frac{3}{4} = ₹ \frac{35}{4}$

Cost of a pen =

$₹10 \frac{2}{5} = ₹ \frac{52}{5}$

Total cost of both the articles =

$₹( \frac{35}{4} + \frac{52}{5} ) = ₹( \frac{175 + 208}{20} )$

$= ₹ \frac{383}{20} = ₹19 \frac{3}{20}$

Hence, Tanvi should pay $₹ 19 \frac {3}{20}$ to the shopkeeper.
